Groupon avoids redeeming vouchers for restauarant

We bought a voucher for Vicky Christans Camps Bay, and booked for the restaurant on 6th August but the restauarant contacted us to say they were closed for 3 weeks due to an emergency kitchen problem. In order to re-book, Groupon needs to remove our booking from their very incvonvenient internet booking system - the previous system of booking via a human being at the restaurant was much easier. (In future I will avoid buying any vouchers linked to this booking system!)<br> <br> Over the last 2 weeks, I have sent Groupon about 6 e-mails/reminders and they have not sent a single reply to any of them. They say they are swamped with complaints but this is ridiculous! Are they trying to avoid redemption and keep customers' money? Are they desparate for funding?<br> <br>
